dc.description.abstract | Sky surveys represent a fundamental data source for astronomy. Radio surveys, as well as pointed observations, performed with interferometers might be affected by the so-called zero-spacing problem when observing extended sources at relatively high frequencies. This problem cause the most extended features in the source to be filtered out due to the lack of antenna-pairs with small separations. Here we show that interferometric survey data can be successfully combined with pointed observations performed with a single-dish telescope to produce images with high resolution and correct total power information.Sky surveys represent a fundamental data source for astronomy.
